Capabilities of a magnetic adiabatic calorimeter in measurement technology

The design of a magnetic calorimeter for the measurement of releases of energy that correspond to a number of rare events, for example, cosmic particles, particles of dark matter, isolated x-ray quanta, and so on, is proposed. The calorimeter is set into a working state by means of the method of adiabatic demagnetization and the response to energy release is measured by a quantum interferometer (squid). The action of the calorimeter in different practical problems is considered, and the sensitivity of the device and its measurement precision are estimated.
